Nutrient agar is a general-purpose solid medium supporting growth of a wide range of non-fastidious organisms. It typically contains ( mass/volume ): [ 1 ] 0.5% peptone – this provides organic nitrogen
LB medium bottle and LB agar plate Plate medium agar LB. Lysogeny broth (LB) is a nutritionally rich medium primarily used for the growth of bacteria. Its creator, Giuseppe Bertani, intended LB to stand for lysogeny broth, [1] but LB has also come to colloquially mean Luria broth, Lennox broth, life broth or Luria–Bertani medium. [2]
An agar plate – an example of a bacterial growth medium*: Specifically, it is a streak plate; the orange lines and dots are formed by bacterial colonies.. A growth medium or culture medium is a solid, liquid, or semi-solid designed to support the growth of a population of microorganisms or cells via the process of cell proliferation [1] or small plants like the moss Physcomitrella patens. [2]
One method of microbiological culture is liquid culture, in which the desired organisms are suspended in a liquid nutrient medium, such as Luria broth, in an upright flask. This allows a scientist to grow up large amounts of bacteria or other microorganisms for a variety of downstream applications.
Super Optimal Broth (SOB medium) is a nutrient-rich bacterial growth medium used for microbiological culture, generally of Escherichia coli. This nutrient-rich microbial broth contains peptides , amino acids , water soluble vitamins and glucose in a low-salt formulation.
It grows in Granada medium as red colonies, and most of the accompanying bacteria are inhibited. Hektoen enteric agar is designed to isolate and recover fecal bacteria of the family Enterobacteriaceae. It is particularly useful in isolating Salmonella and Shigella. Lysogeny broth is used to culture Escherichia coli. [10]
Tryptic soy broth or Trypticase soy broth (frequently abbreviated as TSB) is used in microbiology laboratories as a culture broth to grow aerobic and facultative anaerobic bacteria. It is a general purpose medium that is routinely used to grow bacteria which tend to have high nutritional requirements (i.e., they are fastidious ).
A nutrient agar may be permissive, allowing for the cultivation of any non-fastidious microorganisms; a commonly-used nutrient agar for bacteria is the Luria Bertani (LB) agar which contains lysogeny broth, a nutrient-rich medium used for bacterial growth. [40]
